# Edit YARN site XML file

If you are using YARN, you must verify that the following parameters are set in the `yarn-site.xml` file.

Perform the following steps to edit the `yarn-site.xml` file:

1. Navigate to the `*<username>*/.pentaho/metastore/pentaho/NamedCluster/Configs/*<user-defined connection name>*` directory and open the `yarn-site.xml` file.
2. Add the following values:

   | Parameter                              | Value                                                                                        |
   | -------------------------------------- | -------------------------------------------------------------------------------------------- |
   | **yarn.application.classpath**         | Add the classpaths you need to run YARN applications. Use commas to separate multiple paths. |
   | **yarn.resourcemanager.hostname**      | Change to the hostname of the resource manager in your environment.                          |
   | **yarn.resourcemanager.address**       | Change to the hostname and port for your environment.                                        |
   | **yarn.resourcemanager.admin.address** | Change to the hostname and port for your environment.                                        |
3. Save and close the file.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.pentaho.com/install/9.3-install/pentaho-configuration/tasks-to-be-performed-by-an-it-administrator/set-up-the-pentaho-server-to-connect-to-a-hadoop-cluster/additional-configurations-for-specific-distributions-connecting-to-a-cluster/advanced-settings-for-connecting-to-a-cloudera-cluster/edit-the-configuration-files-for-users-cloudera/edit-yarn-site-xml-file.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
